Intel Core i5-11400H vs AMD Ryzen 5 6600H
Intel Core i5-11400H
► remove from comparison
The Intel Core i5-11400H is a high-end hexa-core SoC for gaming laptops and mobile workstations. It is based on the Tiger Lake H45 generation and was announced in mid 2021. It integrates six Willow Cove processor cores (12 threads thanks to HyperThreading). The base clock speed depends on the TDP setting and at 45 Watt is at 2.7 GHz. The single core boost speed can reach up to 4.5 GHz, all cores can reach up to 4.1 GHz. The CPU geatures 12 MB L3 cache and supports DDR4-3200 memory.
Furthermore, Tiger Lake SoCs add PCIe 4 support (20 lanes in the H45 series), AI hardware acceleration, and the partial integration of Thunderbolt 4/USB 4 and Wi-Fi 6E in the chip.
The SoC features an improved Gen 12 graphics adapter called UHD Graphics with 16 EUs.

Performance
The average 11400H in our database matches the Ryzen 5 5600U and the Core i7-10750H in multi-thread performance, rendering the Core i5 a decent mid-range option as of mid 2022. It isn't as fast as the mighty Ryzen 9 5900HS, yet it will let you run most games in High or even Ultra settings at 1080p if mated to a fast graphics card.
Thanks to its decent cooling solution and a long-term CPU power limit of 45 W, the Gigabyte G5 GD (2021) is among the fastest laptops built around the 11400H that we know of. It can be around 20% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.
Power consumption
This Core i5 series chip has a default TDP of 35 W to 45 W, the expectation being that laptop makers will go for a higher value in exchange for higher performance. Either way, an active cooling solution is a must for a CPU like this.
The i5-11400H is manufactured on Intel's 3rd generation 10 nm process marketed as SuperFin for below average, as of early 2023, energy efficiency.
AMD Ryzen 5 6600H
► remove from comparison
The AMD Ryzen 5 6600H is a processor for big (gaming) laptops based of the Rembrandt generation. The R5 6600H integrates six of the eight cores based on the Zen 3+ microarchitecture. They are clocked at 3.3 (guaranteed base clock) to 4.5 GHz (Turbo) and support SMT / Hyperthreading (12 threads). The chip is manufactured on the modern 6 nm TSMC process.
The new Zen 3+ is a refresh of the Zen 3 architecture and should not offer a lot of changes. The chip itself however, offers a lot of new features, like support for USB 4 (40 Gbps), PCI-E Gen 4, DDR5-4800MT/s or LPDDR5-6400MT/s, WiFi 6E, Bluetooth LE 5.2, DisplayPort 2, and AV1 decode.
In the 6000 series, AMD finally switched to the current RDNA 2 graphics architecture for the iGPU. The 6600H only offers the slower Radeon 660M with 6 of the 12 CUs enabled and 1.9 GHz max. clock speed.
Performance
The average 6600H in our database is in the same league as the R7 5825U, the R7 6800U and also the Core i5-1340P, as far as multi-thread benchmark scores are concerned. This is a very decent result, as of late 2022.
Your mileage may vary depending on how high the CPU power limits are, and how competent the cooling solution of your system is.
Power consumption
This Ryzen 5 series APU has a default TDP, also known as the long-term power limit, of 45 W. A high-performance cooling solution is a must for a system built around such a chip.
The R5 6600H is built with TSMC's 6 nm process for great, as of early 2023, energy efficiency.
